Consistently use unsigned short for network ports
Network ports are now consistently stored as unsigned shorts, apart from
the options and user interface, where -1 is still used to denote the use
of default ports.
Test-Information:
Unit tests pass on macOS 10.13 and Debian 9
On macOS: tested the UI with various proxy and manual ports, behaviour
as expected.
